Reports from the Projects

NOVA (Argentina)

ArVO (Armenia)

AstroGrid (United Kingdom)

ASVO (Australia)

BRAVO (Brazil)

China-VO

CVO (Canada)

ESA (Europe)

Euro-VO (Europe)

GAVO (Germany)

GAVO's Heidelberg data centre keeps adding resources at a rate of a few per semester; a particularly fun one was a service to collect ground-based amateur observations of the Gaia spacecraft during its high-brightness phase in early 2025 (http://dc.g-vo.org/citigbot/q/browse/form).

We maintain and support our data publication package DaCHS. Quite a bit of work went into type-annotating several areas of its source code with the goal of making it more suitable for community development. It also now returns VOTable 1.5 by default, and we have added a management interface for persistent TAP uploads.

We keep co-operating with Germany's national research data infrastructure NFDI, for instance by bringing the VO's DocRegExt records into a format suitable for DALIA (https://dalia.education/en) and uploading them there (provided there's a proper license on them). We also have put in a major grant application to the ErUMData funding scheme with a goal of moving our data centres to the new DZA.

Among our contributions to pyVO, there is a registry constraint on UAT keywords that includes semantics-based query expansion (https://blog.g-vo.org/a-new-constraint-class-in-pyvo-s-registry-api-uat.html); this meshes nicely with our continued involvement in the UAT steering committee.
